Thanks for copy of Smith's "Introduction to Botany". Reports from his excursion into Yorkshire: wishes Smith had been with him at the "dropping well" at Knaresborough, there were jungermanniae, lichens, and mosses; found 'Inula helerium' and 'Sedum telefitium' in a hedge bank, 'Atropa belladonna' in churchyard near Ferrybridge, Yorkshire, and in hedges near the town, and 'Colchium autumnale' in meadows about Knaresborough. Recounts anecdote in Dr [Thomas] Zouch's [(1737-1815)], prebendary of Durham and FLS, unpublished "Memoir of the life of Dr John Sudbury", dean of Durham in 1661, about the detainment of the cathedral library's copy of [John] Gerard's "Herbal" by Colonel Robert Lilburn; thinks it curious in showing the estimation in which the book was held. Invites the Smiths to visit for the Bury Fair.
Postscript by Lady Cullum repeating Cullum's invitation.
